About the Apple T2 Security Chip

The Apple T2 Security Chip brings a new level of integration and security to Mac.

The Apple T2 Security Chip is Apple's second-generation, custom silicon for Mac. By redesigning and integrating several controllers found in other Mac computers—such as the System Management Controller, image signal processor, audio controller, and SSD controller—the T2 chip delivers new capabilities to your Mac.

For example, the T2 chip enables a new level of security by including a secure enclave coprocessor that secures Touch ID data and provides the foundation for new encrypted storage and secure boot capabilities. And the T2 chip's image signal processor works with the FaceTime HD camera to enable enhanced tone mapping, improved exposure control, and face-detection–based autoexposure and auto white balance.
